Handling when downloading is interrupted

[1223334444abc]

At present, when the script encounters an incomplete image for download, it will directly store an incomplete image.

I hope that if the script encounters any download interruption or download error, it can automatically retry until the download is successful (rather than just skipping). At present, I have no idea where the download error occurred.

I am currently very concerned that I may need to use an image integrity check script to check the entire database.
